Differential pressure sensor DPC200-MOD series

membrane0-10 VModbus RTU

Differential presssure / volume flow controller Electromechanical diaphragm measuring system Configuration via Modbus communication Selectable measurements (differential pressure or volume flow) Selectable units (Pa / InH20 or m3/h or cfm) Selectable control mode or measuring mode Control mode with adjustable: setpoint, maximum output voltage, P and I parameterd for PI-algorithm, direct or inverse sense Adjustable k-factor for volume flow calculation The DPC200-MOD has been developed to bundle functions needed in the HVAC industry into one device. As a precise differential pressure sensor it can transmit measurements for both pressure and air flow. The integrated PI control logic is an important component in decentralized closed loop control systems, where pressure and air flow have to be constantly controlled. The additional Modbus RTU interface is intended for the digitalisation of industrial processes. All device parameters can be read and written with the Modbus RTU interface. For direct analog processing, a 0 … 10 V signal output is available. This signal can be configured as a linear / square root measuring signal, or as a manipulated variable of the closed loop controller. It can be used, for example, in air-conditioning technology for controlling fans, monitoring room pressure or controlling filters.
